Brooklyn Blackout Cake Recipe: Rich Chocolate Layer Cake

The Brooklyn Blackout Cake stands as a monumental achievement in chocolate dessert history, celebrated for its intense cocoa flavor, velvety pudding layers, and signature crumb exterior. Originating from Ebinger’s Bakery in Brooklyn, this cake has captivated generations with its decadent profile, featuring moist chocolate layers sandwiched by a thick chocolate pudding and finished with crushed cake crumbs.

Origins of the Brooklyn Blackout Cake Phenomenon

During World War II, blackouts were enforced in New York City to prevent enemy aircraft from spotting lights, plunging the boroughs into darkness. Ebinger’s Bakery, a beloved institution in Brooklyn since 1898, responded by creating a cake so dark and chocolate-rich it mirrored the wartime measures—hence the name ‘Blackout Cake.’ This treat became an instant hit, with lines forming daily for slices of its fudgy glory.

Ebinger’s closed its doors in 1972, but the recipe lived on through devoted fans who reverse-engineered it. Today, bakers worldwide recreate this icon, adapting it with modern techniques while preserving its essence: three layers of devil’s food cake, chocolate pudding filling, and a frosting made from the same pudding mixed with butter and chocolate.

Essential Ingredients for Authentic Flavor

Success with Brooklyn Blackout Cake hinges on high-quality ingredients, particularly Dutch-process cocoa for its deep, mellow chocolate taste. Here’s a breakdown of key components:

• Dutch-process cocoa powder: Provides the signature dark color and smooth flavor without acidity.
• Buttermilk and oil: Ensure moistness and tenderness in the cake layers.
• Chocolate pudding base: Cooked from scratch with sugar, flour, cocoa, milk, and vanilla for a thick, custard-like filling.
• Bittersweet chocolate and butter: Transform the pudding into a spreadable frosting.
• Cake crumbs: One layer crumbled and toasted for the exterior coating.

3. Cool to room temp (30 minutes), cover surface with plastic, chill 2 hours until set.

Devil’s Food Cake Layers

1. Preheat oven to 350°F. Grease and line three 9-inch pans with parchment.
2. Bloom 1/2 cup Dutch cocoa and 1 tsp instant coffee in 1 cup hot water. Let cool.
3. Beat 2 eggs and 2 cups sugar 3 minutes. Add cocoa mixture.

Assembly and Frosting

1. Crumble one cooled layer into crumbs, spread on sheet, toast at 350°F for 10 minutes. Crush fine.
2. Beat chilled pudding with 1 lb softened butter (in thirds) and 12 oz melted bittersweet chocolate until fluffy.
3. Level remaining cakes, slice each horizontally for four thin layers.
4. Stack: cake, pudding, cake, pudding, cake. Frost exterior, press crumbs all over. Chill 1 hour to set.

Pro tip: For clean slices, freeze assembled cake 30 minutes before cutting.

Common Challenges and Pro Baking Tips

Baking Blackout Cake can be tricky due to its components. Here’s how to troubleshoot:

• Pudding too thin? Cook longer or use cornstarch boost (1 tbsp).
• Cake dry? Don’t overbake; aim for moist crumb test. Measure flour by weight (300g per cup).
• Frosting grainy? Ensure butter is soft, not melted, and chocolate cooled.
• Crumb coating uneven? Chill frosted cake first; use a turntable and offset spatula.

Advanced variation: Add espresso powder to pudding for depth, or swap half milk for heavy cream in cake batter for extra richness.

Historical Recreations and Modern Twists

King Arthur Flour’s version emphasizes ganache frosting, while vegan adaptations from bakers like Fran Costigan use whole wheat pastry flour and maple syrup. Some infuse Kahlua into the filling for a boozy kick.

Healthier tweaks include reducing sugar by 25% or using dark chocolate (70% cocoa) to cut sweetness while boosting antioxidants.

Pairing Suggestions and Serving Ideas

Serve at room temperature for optimal texture. Pair with:

• Black coffee or espresso to cut richness.
• Fresh raspberries for tart contrast.
• Vanilla ice cream for a la mode indulgence.

Portion generously—this cake is dense and satisfying in small wedges.

Frequently Asked Questions (FAQs)

What’s the difference between Dutch-process and natural cocoa?

Dutch-process is treated with alkali for milder flavor and darker color, essential for Blackout Cake’s fudgy profile.

Can I make this cake ahead?

Yes! Bake layers up to 2 days ahead, wrap tightly. Assemble day-of or refrigerate up to 3 days.

Is there a gluten-free version?

Substitute 1:1 gluten-free flour blend and add 1/2 tsp xanthan gum. Test batter thickness.

Why toast the cake crumbs?

Toasting dries them out, preventing sogginess and adding nutty flavor.

How do I store leftovers?

Refrigerate in airtight container up to 5 days. Freeze slices up to 1 month; thaw overnight.
